Today is the Vernal Equinox, which marks the first day of Spring. Since the Winter Solstice back in December, the sun's daily path across the sky has been gradually moving northward. Today it reached the halfway point (equinox) on its way to the Summer Solstice - which will mark its furthest point north in June.
If you compare the pictures of the Vernal and Autumnal Equinoxes, you can see the sun is in the same position on the horizon.

During the time of Vernal (Spring) and Autumnal (Fall) Equinox, the amount of daylight and darkness hours are equal. As the sun moves farther north, there will be more hours of daylight in the Northern Hemisphere.
"Spring is the time of plans and projects."
~ Leo Tolstoy, Anna Karenina
